I would say, to your first statement, look at the situation on the border. If you want to badly enough, anyone CAN move. We've got people coming over the border with nothing more than the shirt on their back.
Governments will always bow to businesses needs rather than slum dwellers, so there goes any hope of competent enforcement of the regs. (I'm assuming that you're referring to environmental and anti-pollution regs?)
